MACHINERY FOR SPINNING AND DOUBLING FIBROUS SUBSTANCES.

SPECIFICATION forming part of Iletters Patent No. 705,774., dated July 29, 1902.

Application filed October 11, 1901. Serial No. 78,337. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE HENRY MIL- WARD, a subject of the King of Great Britain,

residing at Agnes Street Meadows, Nottirigham, in the county of Notts, England, have invented new anduseful Improvements in Machineryfor Spinning and Doublin g Cotton, W'ool, and other Fibrous Substances, of which the following is a specification.

Thisinvention relates to improvements upon certain parts of the machinery for spinning and doubling cotton, Wool, and other fibrous substances by the process known'as ring or continuous? spinning, for which Letters Patent of the United States of America were granted to me, No. 675,396, dated June The present improvements relate, first, to improved apparatus for supporting the upper part of the spindles'in their bolsters and imparting a diiferential drag thereto, which is more suitable for heavier classes of work 5 secondly, to improved means for regulating the said difierential drag tothe varying diameter of the cop as it-isbein g built up, and, thirdly, to improvements in the bearing for the carrier studs and bowls for supporting the center wharve or ring for driving the traveler-rings in such machines. I

The drawings hereto annexed show only so' much of a ring-frame with myimprovements applied thereto as is necessary to make them clearly understood, the general construction and arrangement of the machine being the same as that described in my previous speci fication above referred to.

Figure 1 on-the annexed drawings is a vertical section, and Fig. 2 a horizontal section,

half on the line A B and half on the line 0 D, of one modification of myimproved ar rangement for supportingthe spindles in 9 is'a sectional plan View of Fig. 9. Fig. 9 is a view of part of Fig. 9 with portions of the frame broken away.

Referring first to Figs. 1, 2, 3, 4, 5, 6, 7,- and 8, A is partof the frame, B the stationary ring rail, and C the spindle rail, which is mounted and fitted in precisely the same way as described in my former specification. For

the purposes of my present invention the upper'part of the spindle D is carried in an upright pillar or bolster E,j fixedinthe lifter or spindle rail Q but thecup and ball bearings mentioned in my previous specification are replaced by a series of cylinders F, with coned endsrunning inside the pillar or bolster E, and, according to Figs. 1 and 2, carried by a cylindrical ring F which is inserted in the bolster E and has its inside coned to the same ing affixed to the foot of the bolster E and the said weight being moved by the rail Q along the horizontal lever N as the yarn is wound on, as before 5" but in this case. the movement of the weight P causes a variabledrag or friction'on the spindle D by gripping the coned ends of the cylinders F between the ring F beforementioned, and an adjustable collar F at the top of the bolster, the inner side of the bore of "which is coned to the same angle as the ring F and the ends of the cylinders F. In the modification illustrated by Figs. 3 and 4 the supports G are outside the bolsters, made with or fast to the upper coned ring F, and the bottom coned ring F being stationary. In this case the fulcrum of the lever drag-weight lever N would of necessity be fixed on the opposite side of the bolster E.

Figs. 5 and 6 show a modification in which three L-shaped supports G are carried up to the top of the bolster E in recesses or slots, an adjustable collar F at the top being formed with the requisite cone on the under side, the ends of the three connections G be ing made to correspond and the spindle D being gripped with avarying friction caused by the movement of the drag-weight on the horizontal lever N, as before, or the same may be reversed, as shown at Figs. 7 and 8, the bevel or cone being formed on the under side of the shoulder of the connection G, the bottom of the recess or shoulder in the bolster being coned to correspond and the fulcrum of the drag-weight lever N placed in the reversed position.

The arrangement for moving the dragweight P along the horizontal lever N, as described in my former specification, is only adapted to build up a cop-bottom with a straight-sided cone; but in cases where it is required to be built with a partially curved side, according to the second part of my present invention, I regulate the position of the said drag in the manner illustrated by Figs. 9, 10, and 11.

Inside the flanged edge of the gearing end of the frame A and clear of the front rollerwheel a vertical slide Q is fixed, which is connected bya rod R andjoint S at the bottom end to a lever T,which is carried on a stud U in the bottom cross-rail and in the center of the width of the frame. This lever T is actuated by a builder V and works with it, being coupled thereto by a bowl W and bracket Xin such a manner as to have a greatly-increased movementthat is, say, about five inches to one and a half inches of the builder. The face of the vertical slide Q has on it a horizontal cross-slide Y, mounted in suitable guides, (see Figs. 9 and 9 and the vertical slide Q carries in a recessed-out portion of its body in about the center of its vertical length a swivel-bearing Z fora shaft 1,on the end of which a small spur-pinion 2 is fixed and which gears into a toothed rack 3 on the inside of the cross-slide Y. This shaft 1 hangs from the vertical slide Q at the side of the rod R, connecting the said slide Q to the lever T before mentioned, and this shaft 1 is inside a tube 4, in which it is free to slide vertically, but revolves with it, being driven by a cotter or key working in a slot 5, the bottom end of this tubular shaft 4: being carried by a bracket 6 on the end of the builder V and geared to the spindle carrying the change-wheel for the winding-up motion of the builder by worm-wheels 8 in such proportion that the pinion 2 will move the crossslide Y the length of its traverse while the cop-bottom is being formed. The shaft 1 will however still revolve until the cop is finished, and to obviate the difiiculty of the continuous movement of the cross-slide y the rack 3 is only made just the requisite length, and it is at the end of its traverse, brought up against a spring 3 in such a manner as to always keep the end tooth of the rack in gear with the pinion 2 until it is reversed by the lowering of the bolster-rail 0, when the cross-slide Y being brought against the spring at the reverse end the same movement takes ros/7'74 placeviz.,the rail continues lowering-and when a fresh cop is started the reversal of the builder and pinion 2again moves the cross-slide Y the length of its traverse. The slides 9 and rods 10 move the drag-weights P on the horizontal lever N (corresponding with the slides W and rods or bars Q in my former specification) by means of a hang ing lever 11, having its upper end carried by a stud 12 in the gearing end of the framing A, (see Fig. 10,) nearly opposite to the top of the vertical slide Q. 4 About the middle of the length of the lever 11 a stud and and bowl12 are fixed, which are held up to the former-block 20 on the cross-slide Y by a weight or spring, and the bottom end of this lever is connected by a link 13 to a pin fixed in the slide 9 and to the lever 1i on the end ofarocking shaft 15. Asimilarrocking shaft 16 and lever 17 on the opposite side of the machine are connected by a link 18 and a reversed lever 19 to the opposite slide 9, so that the bars 10, actuating the drag-weights on both sides of the frame, are actuated simultaneously by the action of the builder V. To obtain the requisite movement of the slides 9 and of the rods which move the drag-weights O for giving the desired form to the cop-bottoms, the working face of the cross-slide Y carries a former-block 20, (see Fig. 10,) against the surface of which the bowl 12 works,- and any peculiar form or shape may be given to the former-block to suit any required devel opment in the cop-bottom, and the block 20 can be easily removed and replaced without in any way interfering with the other mech anism.

I claim as my invention 1. In a ring spinning or doubling frame, a spindle, a spindle-rail, a tubular bolster hav= ing a recess in its top, conical bearing-surfaces in the recess and surrounding the spindle, a vertically movable part in the recess, a Weighted lever and means connecting it to said vertically-movable part whereby on the movement of the lever the desired drag is produced on the spindle, sustantially as described.

2. A ring spinning or doubling frame, comprising a spindle, a spindlerail, a pivoted lever, a hollow tubular bolster having a recess in its upper portion, conical bearings in said recess surrounding the spindle, a cone in the lower part of said recess, vertical L-shaped supports in the interior of the bolster with their upper ends acting on said cone, and their outer ends resting on and actuated by said pivoted lever, as and for the purpose described.

3. A ring spinning or doubling frame having drag-weights and levers, in combination with 'a builder, a vertical slide connected to and worked by the builder, a horizontal cross-slide having a rack working across the face of the vertical slide, a hanging shaft, a pinion keyed at the top of the hanging shaft and rotated by the builder, an adjustable rod former-block with an inclined facecarried by the said vertical slide, and a hanging lever pivoted at the top to the frame and provided with a bowl adapted to act against the said inclined face, a series of levers at the lower end of the hanging shaft, slides connected to said levers and adapted to move the drag- Weights along the horizontal levers on which they are suspended whereby they are caused to impart a difierential pressure to the spinw dies as and for the purpose described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE HENRY MILWARD.
